I think this is why humans wear clothing. Our more hairy ancestors got used to looking at each other covered in hair and by the time we were relatively hairless, everyone was like, ewww, gross, look at the homo sapiens with all the skin showing and no hair! WEIRD!!! So, we skinned a bear to wear his hair to look more "normal" and that's where we are today.

Either that, or god gave us a tree of knowledge and a snake tricked the first woman into eating from it so then mankind became aware and embarrassed of their bodies.

Probably one of those.
